tomos right seal install
Right hand seal 036-555 can be difficult to install as you can roll the interior seal spring during install.
Below is the progression to installing the RH seal (you need to get it up over the sharp edge on the crank without rolling the small spring off (part of the seal)).
Cut a small shim out of a soda can and roll over itself. Slide shim up over edge of crank. Twist it counter clockwise as to not cut the inner edge of the seal while climbing the installation shim.
